Glossary guide

Terms can explain a game. They cannot predict one.

RTP, volatility, paylines and features are terms used to describe game mechanics. Use them to read a game more clearly, not to estimate a personal outcome.

Mechanics glossary

Four terms often misunderstood in online pokies.

Technical language can create a false sense of certainty when it is not explained. A term can be useful and still have clear limits. The descriptions below are a way to read a game information panel more carefully.

  • Return to player (RTP)A theoretical long-run measure expressed as a percentage in a game description. It does not guarantee a result in an individual session, a day or a chosen number of spins.
  • VolatilityA broad label about how outcomes may be distributed or vary over time. It is not a prediction of how often an outcome will appear for a particular person.
  • PaylinesThe patterns through which a game may evaluate eligible combinations. The exact structure belongs to the game rules, not to an assumption based on its theme.
  • Feature or bonus roundA named game mechanic. The information panel should explain how it works, while the game rules set out the actual conditions that apply.
  • Bet settingThe amount selected for a spin. It should be chosen from a pre-set entertainment budget, not adjusted in an attempt to change a previous result.

What these terms do not tell you

They do not tell you what the next spin will show. They do not tell you that a bonus feature is due. They do not make a higher spend more sensible. They do not replace a time limit or a personal budget. The most useful thing they do is help you recognise when a claim about a game is more certain than the available information allows.

A better reading habit

Open the game information before you play. Read the paytable or rules if the format is unfamiliar. If a term does not make sense, do not assume the meaning from an advertisement or animation. A clear rule should be easy to find before you decide to continue.

No game term is a reason to chase a loss. A previous result does not create an obligation for a future one to balance it.

“A label describes the game. It does not write the next result.”
